Tracking the molecular dynamics of adaptation with horizontal gene transfer. This project aims to track the dynamics of adaptation with gene exchange by building the first experimental evolution model that can directly observe this process. The acquisition of genes from other strains and species (horizontal gene transfer) frequently underlies bacterial adaptation, but it is unknown how this occurs. This project aims to shift understanding of how microbial populations respond to environmental cha ....Tracking the molecular dynamics of adaptation with horizontal gene transfer. This project aims to track the dynamics of adaptation with gene exchange by building the first experimental evolution model that can directly observe this process. The acquisition of genes from other strains and species (horizontal gene transfer) frequently underlies bacterial adaptation, but it is unknown how this occurs. This project aims to shift understanding of how microbial populations respond to environmental challenges. There are significant benefits to be gained from understanding how microbes adapt in response to climate change and the widespread application of antibiotics, given that microbial populations form intimate associations with humans and sustain all of the world’s ecosystems.Read moreRead less
Contribution of comammox bacteria to soil nitrification. This project aims to understand the diversity, activity and environmental relevance of comammox bacteria, the newly-discovered complete nitrifiers, in Australian soils, and to evaluate their relative contributions to nitrification processes compared to other canonical nitrifying prokaryotes. Nitrogen transformations are pivotal microbial processes, with nitrification largely responsible for nitrogen losses through nitrous oxide emissions a ....Contribution of comammox bacteria to soil nitrification. This project aims to understand the diversity, activity and environmental relevance of comammox bacteria, the newly-discovered complete nitrifiers, in Australian soils, and to evaluate their relative contributions to nitrification processes compared to other canonical nitrifying prokaryotes. Nitrogen transformations are pivotal microbial processes, with nitrification largely responsible for nitrogen losses through nitrous oxide emissions and nitrate leaching in the terrestrial ecosystems. The expected outcomes will develop new knowledge on the comammox bacteria and provide novel insights into refined strategies to manipulate nitrification processes for improved nitrogen use efficiency and sustainable agricultural management.Read moreRead less
